A Mesoporous Metal-Organic Framework with Permanent Porosity

摘要

Recent studies in metal-organic frameworks (MOFs) have focused on the construction of MOFs with permanent porosity for gas storage,separation,and catalysis.These applications hinge on two important properties of MOFs: porosity and stability.So far,almost all reported open MOFs are microporous (with pore sizes <2 urn).The augmentation of their channel sizes to mesoporous range (2-50 nm) still poses a great challenge.Ligand extension is an apparent option,but open MOFs built from large ligands tend to collapse upon guest removal.
